A problem-solving experiment is a learning activity that uses experimental design to solve an authentic problem. It combines two evidence-based teaching strategies: problem-based learning and inquiry-based learning. The use of problem-based learning and scientific inquiry as an effective pedagogical tool in the science classroom has been well…

Model-based inquiry (MBI) is an instructional framework designed around the construction, revision, and testing of models by students to make sense of and explain a phenomenon (Windschitl et al. 2008). Focusing on explaining natural phenomena provides a specific context for students to learn and apply scientific understandings to and can help…

Ecosystems, interacting systems of biotic and abiotic factors, are a fascinating topic in life science. The "Next Generation Science Standards" (NGSS Lead States 2013) recognize "Ecosystems: Interactions, Energy, and Dynamics" (HS-LS2) as one of four overarching ideas in life science that students should understand. Student…

Social justice has gained momentum over the past decades with a surge of attention since March 2020. Among many seeking social justice, individuals with disabilities often are forgotten or excluded. Students with disabilities consistently scored below students without disabilities, in all age categories, on the 2015 National Assessment of…

School closures in the wake of the COVID-19 pandemic led to kids asking pertinent questions about why they were not in school, especially some students suffering financial hardship. Virtual classrooms became the mundane venues for students to piece together the pandemic puzzle and unpack unseen inequities. This article examines disparities that…

At the core of an effective model-based inquiry (MBI) unit is a scientifically rich, complex phenomenon that serves as the reason for engagement and drives student sensemaking and investigations throughout the unit. Engaging in iterative attempts to explain phenomena over the course of an MBI unit allows the opportunity for students to construct…

The National Science Teaching Association (NSTA) and the "Next Generation Science Standards" ("NGSS") have attempted to make planning easier for teachers by creating a common resource bank, but there is no unit design process specifically created for science teachers in a project- and inquiry-based classroom. Without a common…

At the Center for Integrated Access Networks (CIAN), an Engineering Research Center funded from 2008-2018 by the National Science Foundation, the education department worked to develop new and innovative digital resources to engage students in learning science content. One resource created, the CIAN Comic Book, focuses on educating students about…

In response to increasingly diverse student groups in U.S. schools, educational researchers have developed curricula that respond to students' unique needs, cultures, and experiences. Curricula that embrace a pedagogy of empowerment are known as Culturally Responsive Curricula (CRC), and such curricula specific to science are referred to as…

Although the existence of and access to clean water are essential for sustaining life on Earth, multiple studies have demonstrated students' nascent understanding of basic water principles. Students have misconceptions related to the water cycle (Ben-zvi-Assarf and Orion 2005), groundwater (Dickerson and Dawkins 2004; Covitt et al. 2009), and the…

Inquiry-based teaching aims to increase student engagement through the development of the hands-on, minds-on skills, such as critical thinking, collaboration, and communication, needed for the 21st century (The Partnership for 21st Century Skills 2015). This approach respects the complexities of the learning process, values the knowledge and…

The primary learning objectives of this "Next Generation Science Standards" (NGSS; NGSS Lead States 2013) aligned activity is to help high school biology students experience firsthand the role of replication in scientific inquiry and food preference as a behavioral reproductive trait of the Madagascar hissing cockroach. The secondary…

How do scientists make inferences for something they cannot directly observe? The Black Box approach seems ideal to help students understand how scientists work. Black Boxes are sealed units; their interior is not accessible. The effort to determine their possible content (internal structure) demands successive modifications in hypothesis,…

Polychlorinated biphenyls (PCBs) are a family of synthetic chemicals consisting of carbon, hydrogen, and chlorine atoms. PCBs have been produced commercially since 1929 in hundreds of industrial applications. Their continued production in the United States was phased out in the late 1970s, and strict disposal guidelines were regulated as adverse…

December 26, 2004 was one of the deadliest days in modern history, when a 9.3 magnitude earthquake--the third largest ever recorded--struck off the coast of Sumatra in Indonesia (National Centers for Environmental Information 2014). The massive quake lasted at least 10 minutes and devastated the Indian Ocean. The quake displaced an estimated…
